Dentistry Preparations TRIZ Cases

A larger precious metal bar is pre-divided into connected small bars, cutting per-unit manufacturing cost while preserving precise mass and easy handling.

A lithium metasilicate-limited precursor machines quickly, then heat treatment converts it into a strong, chemically resistant dental glass ceramic.

Controlled crystal size in a lithium disilicate dental block improves machinability and strength without extra heat treatment.

Preheating above glass transition before UV and visible LED exposure enables complete curing of 3D-printed dental appliances with better stability.

A β-diketone and Type II photoinitiator system enables amine-free curing, reducing discoloration, acid sensitivity, and co-initiator migration.

This dental glass composition reduces reliance on barium while balancing X-ray opacity, refractive index, and mechanical strength.

Yttrium salt dipping modifies zirconia translucency, eliminating ceramic veneers and bond strength failures.

Dissolving solid monomers in solvent before mixing with liquid monomer prevents appearance deterioration while imparting antibacterial properties.

Segmented crystallization creates inhomogeneous phases that mimic natural teeth while reducing tool wear during CAD/CAM machining.

Dissolving solid second monomers in solvent and evaporating the liquid controls particle size to improve cured product appearance and antibacterial properties.

Long-chain silanes reduce shrinkage stress and microcracks in composite moldings by improving filler-matrix interface mobility.

Extruded gutta-percha with oriented carbon nanotubes enhances thermal conductivity and flowing properties.

Selective bleaching of shaded zirconia creates shade gradients without reducing flexural strength or causing warping.

Lithium silicate-wollastonite glass ceramic balances mechanical strength with machining ease, resolving trade-offs in dental restoration processing.

Incorporating ruthenium into a cobalt base alloy resolves the trade-off between cost reduction and functional deterioration in porcelain bonding.

A machinable zirconia composition uses TiO2 nano powder to lower hardness while maintaining strength and fracture toughness.

Embedding organoborane-Lewis base complexes in composite particles prevents premature dissociation and ensures long-term storage stability.

Spiroorthocarbonate crosslinkers reduce polymerization shrinkage stress while maintaining mechanical strength and low odor in dental composites.

Substituting K2O and Na2O with Rb2O and Cs2O lowers crystallization temperature, reducing energy consumption for dental materials.

An ultrasonic irrigation device reduces filling material viscosity and removes air resistance through bubble generation for dense root canal sealing.

Lithium silicate glass ceramic incorporates scheelite and powellite crystal phases to produce distinct fluorescence under UV light.
